In a low velocity fastening system, which component is powered by gunpowder cartridges?

1. Fasteners

2. Pump

3. Boosters

4. Pressure gauge

The correct answer is: Boosters

In a low velocity fastening system, the component powered by gunpowder cartridges is the booster. Boosters are essential for enhancing the energy output of the fastening system, as they utilize the explosive energy from gunpowder to drive fasteners into materials such as concrete or steel. When the gunpowder cartridge ignites, it generates a quick burst of high pressure that propels the booster, which then transfers that energy to the fastener, ensuring that it is driven into the substrate effectively. In contrast, fasteners themselves are the specific components being driven into the material but lack any power source since they do not perform the act of propulsion. The pump is generally used in hydraulic systems and not associated with direct fastening methods. A pressure gauge is a measuring device used to indicate the pressure in a system and does not engage directly in the fastening process. Therefore, the booster is the component that directly utilizes gunpowder cartridges to achieve the fastening action needed in these systems.
